Promavia Jet Squalus / General Avia Jet Squalus / Alberta Aerospace Phoenix FanJet

Jet Squalus

A Belgian enterprise, the Jet Squalus was designed and built around the Garrett TFE109 engine by General Avia in Italy. Designed by Stelio Frati, the prototype Jet Squalus made a successful first flight on April 30, 1987. Three prototypes of the “all through” side by side seat trainer were built and flown to Belgium. The Squalus was promoted as “the first and only third generation global trainer”, offering ab initio and advanced training from one cockpit.

Two proto¬types of the Jet Squalus are being built by General Avia in Italy, the first powered by a Garrett TFE-109 turbofan, and the second by a more powerful Williams International FJ-44. Following completion of initial flight trials the aircraft will be flown to Belgium, where production, marketing, and support of the “all-¬through” jet trainer will be administered by Promavia.

The initial 1,330 lb st (5.92 kN) -1 unit was replaced by the Garrett TFE 109-3 turbofan of 1,600 lb st (7,12 kN).
Light weapons and/or drop tanks can be carried on underwing hardpoints.

No orders had been placed for the aircraft by 1988.

In 1995 the Belgian company Promavia licensed Alberta Aerospace to begin development of an ab initio trainer version of its Jet Squalus, under the name Phoenix FanJet. Eventually Promavia sold Alberta Aerospace the flying Jet Squalus prototype for conversion (to include new Williams- Rolls FJ44 turbofan engine in a revised airframe, new “glass” cockpit, larger flying control surfaces and more), allowing certification in about the year 1999. After Promavia ceased trading, Alberta Aerospace purchased other Promavia assets, allowing eventual production in Canada.

Based in Calgary, Canada, Alberta Aerospace obtained the two prototypes built with plans to install Williams-Rolls FJ44-1a engines. Almost 80% of the structural and stress testing for certification was completed by Frati, who tested the airframe to +7 and –3.5G. With a 140 kt gear extension speed, the aircraft did not meet the 61 kt stall speed required for civilian certification for single engine, so the wing span was to be extended by four feet.

A flight demonstrator was fitted with the Williams FJ44 engine.

Projekt 8 Dolphin

The Danish Dolphin tandem two-seater motor glider was designed and built by the Projekt 8 I/S company of Roskilde, and 10 construction of the prototype was taking place at three separate sites near Copenhagen,
and it was expected that the first flight was to be made late in 1978.

The Dolphin is a cantilever mid-wing monoplane of mixed constrution with a T-tail, powered by a 54hp Volkswagen VW1600 engine driving a two-blade pusher propeller, mounted on a pylon and retracting rearwards behind closed doors into the top of the fuselage aft of the wings. The wings, which have 4° dihedral, have an aluminium centre section and wood and glassfibre outer panels, flaps and ailerons; there are aluminium air brakes in the upper surfaces just ahead of the flaps. The forward fuselage is a welded steel tube framework covered with a light glassfibre shell, and the rear fuselage is a wooden structure reinforced by glassfibre. The tail unit is likewise of wood, with a fixed incidence tailplane, a central trim tab in the elevator and an inset tab at the base of the rudder. There is a semiretractable rubber-sprung mainwheel plus a nosewheel and a steerable tailwheel, as well as retractable wing tip balancer wheels. The one-piece cockpit canopy opens sideways.

Progressive Aerodyne Sea Rey

A side-by-side, high wing amphibian, related to the Adventure Air Adventurer 333. It is a high wing, pusher, tail dragger configuration, and a panoramic lexan cockpit. The wings are swept back at the leading edge with a straight trailing edge to form a tapered wing. The engine is mounted on top of the wing, which is supported above the fuselage by a vertical pylon.

The Cabin is designed with side-by-side seating. Entry into the cabin is through a sliding canopy into the 44 in/112cm cockpit. Dual flight controls enable flying from either seat. There is storage space behind the seats (L48 x W44 x H17 in.) for baggage.

The SeaRey is the ability to fly unaffected with the individual dual sliding canopies either opened or closed. The retractable landing gear handles unimproved grass runways. The take off roll on land at gross weight is about 375 feet (115m). Lift off takes place at around 45-50 mph (40 – 45 knots), and 65-70 mph (55-60 knots) is the best rate of climb speed. Rate of climb is 1,000+ ft per min (300m+ per min) Solo and around 800 feet per minute (245m per min) at gross weight.

In cruise the SeaRey settles at 90 mph (80 knots). Top speed is 113 mph (98 knots). Due to the installation of special leading edge extensions on the wings, the stall is very docile and the aircraft is spin resistant. Upon throttling back and applying 20 degrees of flaps, the aircraft slows to the stall speed of around 40 mph (34 knots). The stall is gentle and straightforward and recovery is conventional. The retractable undercarriage comes with a simple manual system or alternatively an electric mechanism. An over center lock mechanism is a feature of this simple design.

Best approach speed for a water landing is 65 – 70 mph (55-60 knots) with 10 degrees of flaps. Upon reaching short final, 20 degrees of flaps can be initiated to further slow the aircraft’s touch down speed on the water. Landing flare begins lower than conventional land-only aircraft. A nice touch down speed is 45-50 mph (40-45 knots). This lands the aircraft “on step” and produces very smooth contact with the water.

The SeaRey is capable of handling quite rough water conditions but until such time as the pilot has developed their seaplane water experience, operations in moderate conditions with wave size under 12 inches (30cm), is recommended.

With 20 degrees of flaps for takeoff the SeaRey will come “on plane” in around 4 seconds. A further 6 to 8 seconds to get airborne. The hull produces a very flat spray pattern preventing water from going through the propeller. Accelerating to 45-50 mph (40-45 knots) to rotate and lift off. Established in the climb and at a safe height, reduce the flaps to 10 degrees.

The LSA Searay has dual controls with electric trim, and engine options include 65, 74, 80, and 115 hp Rotaxs.

The basic kit was $21,900 less engine in 2000.

By 2012, the American-made SeaRey has been out in kit form for 21 years (600 kits delivered) and was also an S-LSA. The 2012 models were the Sport and Elite S-LSAs, and the LSX kit (E-LSA or EAB). Prices: US$144,000 (Elite); US$125,000 (Sport) and US$34,900 (LSX airframe-only kit).

Pro-Fe Banjo

The Banjo sailplane is of mixed construction. Its 13.3 m (43.6 ft) span wing is strut-braced with one lift strut per side and uses a plywood box spar and spruce wing ribs, with the leading edge of the wing covered in plywood and the rear portion covered in aircraft fabric covering. The nose ribs are expanded polystyrene while the ailerons are made of wood and covered in fabric. The wing airfoil is an SM701 at the wing root transitioning to a Wortmann FX-60-126 at the wing tip, while the tailplane uses a Wortmann FX-71-L-150/30 airfoil. The fuselage is of fibreglass monocoque construction, while its one-piece bubble canopy is made from polycarbonate. The aircraft has fixed monowheel landing gear with a wheel brake and upper wing surface air brakes.

Proctor Kittiwake I / Mitchell-Proctor Kittiwake I

G-ATXN Mitchell-Procter Kittiwake

Originally designed in 1964-65 by R. G. Proctor and C. G. B. Mitchell as a dedicated single-seat glider tug aircraft. Mitchell-Procter Aircraft was set up to produce the Kittwake prototype. It was a development of the Mitchell-Prizeman Scamp design study of 1964. ‘Kit’ Mitchell was the Kittiwake’s designer, with Roy Procter in charge of building it. It had excellent visibility, sturdy landing gear.

The Kittiwake was of all-metal stressed skin construction with tricycle landing gear. The nose-wheel was steerable for taxiing and the aircraft was fitted with hydraulic brakes.

Mitchell-Proctor Kittiwake Under Construction 1 Jan 1967

The aircraft would be capable of aerobatics with a rate of Roll 200 degrees at 103 mph (90 kn; 166 km/h). The Kittiwake had a rate of climb of 700 feet (213 metres) per minute with a 1,000 lb (454 kg) glider in tow.

The single-seat Kittiwake I is an all-metal aircraft, with low cantilever wings of parallel chord built around a single spar carrying 5° of dihedral. NACA single slotted flaps occupy the whole of the trailing edge inboard of the ailerons. The wings attach to a centre section which is integral with the fuselage, a feature intended to help construction in a small space like a garage. The straight tapered fin carries a horn balanced rudder and the constant chord tailplane has a starboard side trim tab.

The Kittiwake’s fuselage is built around four longerons, with flat sides and bottom and single curvature decking. Its overwing cockpit has a rearward sliding canopy and its fixed tricycle undercarriage has cantilever angled steel spring main legs attached to the lower longerons, giving a track of 5 ft 9 in (1.75 m). The Kittiwake I was powered by a 100 hp (75 kW) Continental O-200 engine.

The wing had generous flaps with high operating speeds which allowed for a fast descent. It had a self-starter system, provision for a radio. The Kittiwake also had a mechanism for retracting the tow rope during the descent. This design was fully aerobatic and additional fuel tanks could be fitted to extend the range.

Mitchell-Proctor Kittiwake Under Construction 1966

By the middle of 1965 production tooling were being made for the wing ribs as well as spars machined.

The Kittiwake single-seat, low-wing monoplane was designed to make full use of all-metal materials and modern construction while retaining a simplicity of design that lends itself to homebuilding.

Mitchell-Proctor Kittiwake I G-ATXN Cranfield 22 Jun 2002

The prototype was started at Camberley but completed by BEA Engineering in 1966-7, powered by a Continental O-200-A. First flown at Lasham on 23 May 1967, it was registered G-ATXN PFA.1306. It was re-engined with a fan-cooled Lycoming O-290 at Lasham in 1972. The prototype was later known as the Mitchell-Procter Kittiwake I. Around a year and a half later the partnership was dissolved and plans for home builders were produced by Procter Aircraft Associates.

A second was built at RNAS Lee-on-Solent as an apprentice project under Lieutenant Commander Cudmore, started in 1969. First flying on 21 October 1971 sn serial XW784, at Lee-on-Solent, powered by a Rolls-Royce/Continental O-200-A.

It was subsequently registered G-BBRN. Built, one by Royal Navy apprentices in 1971 for glider towing, a larger diameter (6 ft 4 in, 1.93 m) propeller is fitted, increasing the rate of climb by 24%. A tow release hook is fitted under the tail. Only one Kittiwake II, the prototype, was built.

In later years the prototype was re-engined with a Lycoming O-290-D2 engine.

Mitchell continued development and produced the Mitchell Kittiwake II two-seater. Plans were available for both single-seat and two-seat versions, but only four were constructed. Examples built of the Kittiwake I: G-AXTN, G-BBRN (marked as XW784).

One Kittiwake was active until at least at 2005 and the other is still active. They remain on the UK Civil Register. These are the prototype, G-ATXN and the ex-Naval G-BBRN. The latter is painted, as in its Naval days, as XW784.
